I have never in my life made fresh squeezed lemonade. And I can assure you I will never make it from a powder again.
So, how did we do it? Simple.
Heat a cup each of sugar and water in a saucepan until the sugar has dissolved, then add to a pitcher with a cup of lemon juice. Dilute with 4 cups of cold water and chill.
See, told you it was simple. And delicious.
